First, understand how hormones trigger insulin
“Insulin’s action is the key,” notes Dr. Jason Fung, MD, a nephrologist who is successfully reversing type 2 diabetes in thousands of patients—with the side effect of bringing them down to a healthy weight. In his international bestseller The Obesity Code, Dr. Fung describes how insulin, insulin resistance, and the stress hormone cortisol are the key hormonal triggers to both type 2 diabetes and obesity. To reverse them you need to address those triggers, Dr Fung says, which he does by putting his patients through a regimen of therapeutic fasting in his IDM clinic. This is the right diet if you want to avoid becoming diabetic.
